This was seen as an attempt by Red Bull to out the secrets of Ferrari's success and when the red cars' struggle was put to Max Verstappen, he told Ziggo Sport: "That's what happens when you stop cheating."
Although Wolff was unsure if the TD and Ferrari's lack of pace in the States was linked, he was clear that something had suddenly changed for Vettel and Leclerc.
"Whether it's down to the technical directive or down to another issue, I honestly don't know as we can't look into what Ferrari has done.
"If someone was doing what the technical directive clarified, it would have been foul play.
"The way the technical directive was formulated, it was a severe breach of regulation, so there was not even any talk of grey areas."
Mattia Binotto and Leclerc both staunchly defended Ferrari after the race, insisting that the perceived struggles for pace had nothing to do with something fundamental changing on the SF90.
